Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.3910A>G (p.I1304V) alteration is located in exon 27 (coding exon 27) of the SNED1 gene. This alteration results from a A to G substitution at nucleotide position 3910, causing the isoleucine (I) at amino acid position 1304 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
